Technical Field
The invention relates to a cosmetic composition and a preparation method and application thereof, belongs to the technical field of daily chemicals, and particularly relates to an eye cream composition with an eye pattern removing effect and a preparation method thereof.
Background
The fine lines of eyes refer to small fine lines and wrinkles formed by the fact that the skin of eyes is influenced by external environment to form free radicals, and collagen and active substances in normal cell membrane tissues are damaged by the free radicals and cells are oxidized.
With the aging, the skin is aged, the moisturizing effect and the barrier function of the skin are gradually weakened, the content of natural moisturizing factors is reduced, the skin around the eyes is thinnest, sebaceous glands and sweat glands are not available, the water retention capacity is poor, the water is easy to evaporate, and the skin water deficiency caused by the environment, seasons and self causes is always a major cause of the generation of fine wrinkles of the eyes.
Secondly, with the development of modern society, most people need to face computers and various bad habits such as frequent squinting eyes or blinking, which can easily cause aging of the skin of eyes to generate fine lines. Since both eyes are blinked for more than ten thousand times per day, skin and muscles around the eyes are naturally involved in such frequent blinking, and thus, eyelid slackening and frailty are easily caused, which is also the cause of easy formation of "wrinkles" around the eyes. Overuse of the eyes is also one of the main causes of fine lines around the eyes.
Furthermore, poor ocular blood circulation can also lead to the generation of fine lines. Because the skin of the eyes is thinner, the blood vessels in the opposite skin are thinner and fewer, so that nutrients and oxygen are more difficult to transport into skin cells, and capillary circulation around the eyes is easy to stagnate. In addition, as the age increases, the content of collagen and elastin of skin begins to gradually decrease, the skin lacks enough nutrition and vitality, the nutrition of the eye skin is difficult to supplement, the blood circulation is poor, the metabolism is also difficult, fine lines begin to appear, and finally the skin around the eyes is easy to age and wrinkle.

The results show that the embodiment of the invention has the effects of short wrinkle removal cycle and obvious effect, and compared with the results of the comparative example, the various compositions for removing the eyewinker have synergistic effect.
The eye striae removing efficacy composition consists of snail secretion filtrate, a huperzia starburst algae extract, palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7, and the way of each component to play the role of striae removing is analyzed: the snail secretion filtrate in the composition permeates into subcutaneous tissue layer, collagen and elastin contained therein are effective in maintaining skin elasticity and moisture, and allantoin and glucuronic acid help skin resist free radical, make skin superficial layer of skin's viscose lipid soft, remove old cutin, accelerate cell regeneration, and reduce skin wrinkle and scar.
The extract of the Huperzia serrata is used for moisturizing, improving the repair process of the skin, and improving the adhesion between cells so that the skin tissue is more tightly and completely connected. Palmitoyl tripeptide-1 acts on the dermis layer, can promote the synthesis of extracellular matrixes such as collagen and glycosaminoglycan, strengthen the dermis layer, make the skin thicker, tighten, ease wrinkles and have stronger ultraviolet radiation resistance; palmitoyl tetrapeptide-7 supports the activation of skin repair processes, particularly the mastoid dermis, which is fragile and susceptible to UV damage, smoothing wrinkles while improving skin tone and elasticity.
The various eyeprint removing functional components are mutually synergistic, so that the active components act on the surface layer and the deep layer of the skin of the eyes, which is beneficial to reducing fiber cracking, in particular to helping the reconstruction of fiber reticular tissues of the mastoid dermis layer, effectively enhancing the toughness of the skin, improving the elasticity of the skin, tightening the skin of the eyes, smoothing the eyes and reproducing the youthful luster of the eyes.
